Lead your class to construct a solar still on campus to demonstrate how water can be extracted from the soil. The power of solar energy is emphasized, as is the concept of how capillary water can be recovered and purified by using a...

In this climate science learning exercise, students answer five multi-part questions on the responsibilities of a climate scientist. Students may gain this knowledge through a WebQuest.

Scientists respond to 26 question posed by learners. These experts answer in easy to understand language, include photos to illustrate the issue, offer suggestions for how young people can make a difference, and supply links to resources...

Skeletons may not be able to speak, but they can still tell us a lot. High schoolers watch a short video about the ways biological anthropologists can use a skeleton's bone structure to determine age, gender, place of birth, and social...

Explore how sound travels as waves with a straightforward lesson that explains the basics of waves in relation to sound. The presentation considers sound waves in both open and closed pipes and shows how to calculate wavelength and...
